Canon R5 footage wont drop into Vegas 19 timeline

HeavyMetal wrote on 1/18/2023, 9:19 PM

I have a copy of Vegas 15, and Vegas 18, that these clips drop into no problem, and it worked for a time on Vegas 19, and then one day (maybe after an update?) Vegas 19 just stopped accepting these clips into the timeline off my R5. Not sure why this is, or how to solve it. I didn't specifically notice immediately upon making any changes or updates because I am not always working with R5 clips. Any ideas?

The info of the clips in question is:

@Former user Thanks for pointing that out, I looked at his file the other day and forgot that. I get the same randomness. It can play through with no black frames or dramatic black frame problem like you, or minimal black frames. It behaves just like the iphone 10bit video I posted in the VP20b326 thread

What's your hardware, Todd?

Former user wrote on 1/26/2023, 7:36 PM

@fr0sty Studio driver 528.24, freshly installed tonight tho & haven't restarted PC yet, I'm off to bed now, I'll restart the PC & try it again in the morning, 👍

@fr0sty Amd 5900x Nvidia RTX 3080. I don't think I have the January studio update installed, so I should do that considering this is new release software

Threadripper 2950X

I will say this problem persisted on a previous GPU as well, that being an AMD Vega 56.

It is especially puzzling to me that it drops into the timeline in Vegas 15 and 18 no problem still, as we speak.”

I see two users with AMD cpus and nvidia gpus with the problem.

Suspect:

motherboard bios
chipset drivers
Windows maintenance
GPU firmware and drivers.

@fr0sty It's a GPU decoder problem (NVDEC) , set 'hardware decoder to use' to off, the black frames go away in VP20b326. I'm using latest studio drivers now

I can reproduce the issue on my RTX 2060 laptop by turning of QSV decoding and enabling NVDEC. Reporting to the dev team.

While normally I would agree, this has spanned between several GPU firmwares / physical GPUs themselves, and the motherboard bios/chipset drivers have not changed inside of the timeline of this issue.

NVDEC seems to be our culprit here, it reliably produces errors when enabled.

For my issue not being able to load the clips? NVDEC is an Nvidia thing right?

Just to test, go into preferences, file i/o, and disable decoding on the gpu. Then go into the video tab, and disable the gpu there too... does it still stop you from dropping the media in? I still think that error has something to do with VEGAS being prevented from properly reading those files for some reason... but who knows.

Be sure to restart VEGAS each time you change the GPU settings.

Well there we have it. I went in there to do that, and went 1 option at a time, restart between each. When I got to the checkbox for "Enable legacy AVC decoding", I unchecked it, and the problem is solved. Weird issue. Thank you for helping me root around!

fr0sty wrote on 1/26/2023, 9:17 PM

Yeah, the legacy decoders are not compatible with certain newer formats. Glad it helped!

Funny thing is, we uncovered an actual bug getting to the bottom of this issue, so even though your issue wasn't a bug per se, we still will manage to squash one anyway.

Not all is lost!

@fr0sty @HeavyMetal Yep same here, with the GPU turned OFF in Preferences - File I/O & Video tab the clip played well in VP20
